CARSTEN HANSEN, OF MORGAN, IOIVA.

GATE.

SPECIFICATION forming part of Letters Patent No. 411,437, dated September 24, 1889.

Application filed July 30, 1889. Serial No. 319,202. (No model.)

To all whom, it may concern:

Be it known that I, CARSTEN HANSEN, a citizen of the United States, residing at Morgan, in the county of Crawford and State of Iowa, have invented certain new and useful Improvements in Gates, of which the following is a specification.

My invention relates to that class of swing ing gates which are opened and shut positively by means of levers on opposite sides of said gate; and it consists in various features and details hereinafter set forth and claimed.

In the drawings, Figure 1 is a perspective view of my improved gate and its operating mechanism; Fig. 2, a perspective view showing the parts as they appear when the gate is opened.

A indicates the gate proper, secured by binges B B to a post or support 0, the gate having a pivoted latch D to engage a keeper E on a second post or support F. Latch D is connected by a link a with one arm of an elbow-lever Z), the other arm of the lever being connected by means of a rod 0 with the free end of an arm (I, pivotally secured to the top of the gate or to a plate 6 fastened thereon. This plate c has a lugf to limit the throw of the arm d, as shown.

I-I indicates a bar pivotally connected at one end to a loose collar g, encircling a stud on the outer or free end of arm (I, the other end of the bar being pivotally connected to a second bar I, which is likewise pivotally secured to a collar h, mounted upon the upper end of a post or standard .I. This construction permits the two barsII and I to swing laterally and to move toward and away from each other as the gate opens and shuts.

K indicates a post or standard, to the upper end of which is secured a bracket K, carryingdouble-grooved rollers t and j, which are arranged horizontally therein, as shown in Fig. l. Pivotally secured to the bracket are two bars k and Z, which are pivotally connected, respectively, with similar bars m and n, the latter being pivotally connected with each other and with a swivel-block 0, carried by the bar I. The bars 7t 1 m n form, in effeet, a lazy tongs connection between the bracket and bar I. Bars Z andm are provided with arms 19 and q, to which are secured the chains 4 and 5, each of which is connected with a pair of operating-levers L L or M M, pivoted to posts or standards N and O and provided at their free ends with chains or cords P.

Supposing, now, the gate be closed and it is desired to open the same, the operation will be as follows: By pulling down upon the free end of lever M or M the chain .9, secured there to, will be moved with the lever, and as it is attached to the arm on of the lazy-tongs it brings the pivot of the bars m or toward the pivot of the bars 7c Z. Of course as the bars m n thus move they carry with them the bars H I, one of which H is connected to the arm (Z and moves said bar far enough to cause the latter, through the connections 0,1), and a, to raise the latch D out of engagement with the keeper. A further movement or downward pull upon the lever M or F brings the arms or bars 1% it still closer together, and as the connections a b e (Z can move no farther independently of the gate the latter will be moved bodily upon its hinges. Now, when it is desired to close the gate the lever L or L is pulled downward, when the action described will be reversed and the gate closed positively.

Having thus described my invention, what I claim is- 1. In combination with a gate having a latch, the bars 11 I, serving to operate the latch, the lazy-tongs connected with the bars 11 I, and a pair of levers L M, connected with and serving to operate the lazy-tongs.

2. In combination with a gate having a latch, bars H I, serving to actuate the latch, lazyton gs connected with the bars II I, levers L L M M, arranged in pairs, and chains or cords 'r and 3, connecting the lazy-tongs with the levers.

3. In combination with a gate having alatch, post or standard J, bars H I, serving to operate the latch and connected with a swivelcollar 77., secured to the post or standard, lazytongs connected with bar I by means of a swivel-block 0, levers L M, and connections between the levers and lazy-tongs.

4. In combination with a gate having alatch, post or standard J, bars II I, mounted upon the post and connected with and serving to actuate the latch, bracket K, bars I: I, pivot ally connected with the bracket, bars m n, pivotally connected with bar I and with the bars 70 Z, levers L M, and chains or cords connecting the levers with the arms Z m.

5. In combination with gate A, having latch D, post or standard J, bars H I, mounted upon the standard and connected with the latch through intermediate mechanism, bracket K, bars 70 Z m n, arranged substantially as shown, arms 19 q, secured to bars Z'm, levers L M, and chainsr s, all arranged substantially as shown.

6. In combination with gate A and latch D, block or arm d, mounted upon the gate and connected with the latch, arms H I, connected, respectively, with the arm d and a post or I5 standard J, bracket K, bars 70 Z m 11, connected in pairs with each other and with the bracket and arm I, levers L M, and chains or cords r and s.

In witness whereof I hereunto set my hand 20 in the presence of two Witnesses.
